Description
Engine Gasket Kit for GY6 150cc Engines
This gasket kit suits the 57.4mm bore GY6 150cc setup, specifically the 157QMJ model. It supplies every sealing piece needed for a full engine rebuild, so you can fit new seals rather than reusing worn ones. The kit includes a CVT cover gasket for short-case motors, which makes it a practical pick among GY6 150cc scooter parts.
Full Gasket Selection
The kit covers head, base, intake, exhaust, valve-cover, and timing-chain gaskets. Every piece is cut to the dimensions and profile needed for the 157-series GY6-A engine, which helps achieve a snug seal and steady running.
Short-Case CVT Gasket
The set includes a 16-inch CVT cover gasket made for short-case builds, the type often used on scooters with smaller rear wheels and across a range of GY6 applications. Correct fitting of this gasket helps keep the CVT assembly sealed and working as intended.
